kanut, you run 275/60/15’s on your GN right? do you get any rub on the frame or on the outter lip of the wheel well? what backspacing do you need to run those? Anyother G-body guys run that size as well? It seems like its hit or miss with that combo on a g-body. My pops was gonna put some BFG’s on the GS instead of the radial Gt’s so now i have (2) 275/60/15’s and (2) 255/60/15’s to use on something. Obviously the 255’s are too big for the fronts on a g-body becasue even my 235’s rub but if i can’t use the 275’s for the rear i’ll use the 255’s. the 255 are brand new and the 275’s only have about 1000 miles and one good burnout on them. ---

255 will do good on the back. i use 275/50/15s drag radials but have 4.5" back spacing and a custom 10inch rim. gnx suspension helps but i think the biggest disadvantage on a gbody buick is the wheel well lip moulding because it sticks in further . im not sure you have that thou ---

I run 275/60/15 nittos all the time on my GN, if you seen my car, u seen how it looks with them. You need atleast 3.5 inches of back spacing i believe, and 8 inch wide rim, thats what mine are. I did have some rubbing problems around turns, but i got a set of airbags in the rear springs and no more rub… hope this helps… an upgraded rear sway bar would help with the rub also. ---
